This application is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2020-0016825, filed on Feb. 12, 2020, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety.
The disclosure relates to an electronic apparatus and a control method thereof. More particularly, the disclosure relates to an electronic apparatus for summarizing a plurality of sentences and a control method thereof.
Various technologies for summarizing documents have been developed recently. One of the technologies is a technology for searching words having a meaning similar to a word used in a title in a body of a document and summarizing a document focusing on the searched words. Additionally, a user's preference may be reflected to summarize a document based on information such as the number of times a user accesses a link of another document including the words used in the title, a user's gender, age, or the like.
However, these technologies may only be applicable to relatively short writings with a clear title. That is, these technologies may be applicable to only a document in a type similar to a news article, and in the case of a document, such as a literary work, of which entire writing is long or which is composed of several paragraphs having a similar level of importance, critical contents are likely to be omitted.
Even if whether to summarize is determined based on the information of a user's gender, age, or the like, the user's preference may not be accurately reflected. Even if the user's preference is recognized by the number of accesses of a user to a link of another document including the words used in a title of a document, there may be a disadvantage that a clear method of determining which content should be omitted and which content should be summarized is not provided.
There is a need to develop clear guideline that can clearly reflect a user's preference, and how to summarize a document.

The electronic apparatus 100 is an apparatus for summarizing a document and may be an apparatus to output a summarized document as a sound, such as a speaker. The speaker may be a configuration of another device such as a television (TV), a desk top personal computer (PC), a notebook, or the like.
The electronic apparatus 100 may be an apparatus which includes a display such as a TV, a desktop PC, a notebook PC, a video wall, a large format display (LFD), a digital signage, a digital information display (DID), a projector display, a digital video disk (DVD) player, a smartphone, a tablet PC, a monitor, a smart glasses, a smart watch, and directly displays a summarized document.
The electronic apparatus 100 may be an apparatus which is not equipped with a speaker or a display, such as a set-top box (STB), a computer's main body, or the like, and may be an apparatus which provides the summarized document to a device or display device provided with a speaker. However, embodiments in accordance with this disclosure are not limited thereto and any apparatus that may summarize a document is available as the electronic apparatus 100.
The document includes a plurality of sentences, and summarizing of the document may mean deleting some of the plurality of sentences or changing each of the plurality of sentences to a shorter sentence. Alternatively, a summary of the document may refer to extracting and reconstructing a significant content from a plurality of sentences.
Referring to
The memory 110 may refer to a hardware that stores information such as data as an electric or magnetic form so that the processor 120, or the like, may access, and the memory 110 may be implemented as at least one hardware among a non-volatile memory, a volatile memory, a flash memory, a hard disk drive (HDD) or solid state drive (SSD), random access memory (RAM), read-only memory (ROM), or the like.
The memory 110 may store at least one instruction, program, or data used for operation of the electronic apparatus 100 or the processor 120. The instruction is a code unit that directs the operation of the electronic apparatus 100 or the processor 120, and may be written in a machine language that can be understood by a computer. A module may be an instruction set of a series of instructions that perform a particular task of a task unit.
The memory 110 may store data which is information in bit unit or byte unit that may represent characters, numbers, images, or the like. For example, the memory 110 may store data such as a document including a plurality of sentences.
Information about a type which a word represents may be stored in the memory 110. For example, a word “wind” may be expressed as a type such as “weather (10)”, “context (4)”, and “description (2)”, and the memory 110 may store words and information that a type matches the word. The number in the parenthesis of each type may refer to a score for the word, and the higher the score, the more appropriate as a type of the word. For example, for the “wind”, “weather” type of which score is 10 may be more suitable rather than “context” of which score is 4 and “description” of which score is 2. Although the word “wind” is described, the memory 110 may store the plurality of words and information that a type corresponding to each of the plurality of words matches a plurality of words, and this information can be a predefined state. However, a score of a type matched with each of the plurality of words may be updated in a summary process of the document.
A user's preference for each type may be stored in the memory 110. For example, the memory 110 may store a user's preference for a type of “weather”, a user's preference for a type of “context,” or the like. The user's preference may be a state set to not perform a summarization until the user's interaction is entered. Thereafter, a summary operation or a skip operation may be further performed by increasing or decreasing the user's preference according to the user interaction.
The AI model may include a plurality of neural network layers. Each of the layers includes a plurality of weight values, and may perform a neural network processing operation through an iterative operation leveraging results of a previous layer and a plurality of weight values. Examples of a neural network includes convolutional neural network (CNN), deep neural network (DNN), recurrent neural network (RNN), restricted Boltzmann machine (RBM), deep belief network (DBN), bidirectional recurrent deep neural network (BRDNN), deep Q-networks, or the like. In the disclosure, various neural network may be used in addition to the neural network mentioned. The AI model may be configured with an ontology-based data structure which is represented as a format in which various concepts, conditions, relations, or agreed-upon knowledge are represented as a format processible by computer.
The AI model may be trained through a separate server and/or system or the electronic apparatus 100 using various learning algorithms. Learning algorithm is a method of training a predetermined target device (e.g., robot) using a enough learning data so that the predetermined target device can make a decision or prediction by itself. Examples of learning algorithms include, but are not limited to, supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning, and various learning algorithms may be used.
The memory 110 may be accessed by the processor 120, and reading/writing/modifying/updating of data by the processor 120 may be performed associated with the instructions, modules, AI model or data.
The processor 120 may control overall operations of the electronic apparatus 100. The processor 120 may be connected to each configuration of the electronic apparatus 100 to control overall operations of the electronic apparatus 100. For example, the processor 120 may be connected to a memory 110, a speaker (not shown), a microphone (not shown), a display (not shown), a communication interface (not shown), or the like, for controlling the operation of the electronic apparatus 100.
The processor 120 according to an embodiment may be implemented with a digital signal processor (DSP), a microprocessor, and a time controller (TCON), or the like, but the processor is not limited thereto. The processor 120 may include, for example, and without limitation, one or more among a central processor (CPU), a micro controller unit (MCU), a microprocessor unit (MPU), a controller, an application processor (AP), a communication processor (CP), an advanced reduced instruction set computing (RISC) machine (ARM) processor, a dedicated processor, or may be defined as a corresponding term. The processor 120 may be implemented in a system on chip (SoC) type or a large scale integration (LSI) type which a processing algorithm is built therein, application specific integrated circuit (ASIC), or in a field programmable gate array (FPGA) type.
The processor 120 may identify a type corresponding to each of the plurality of sentences included in the document, group the plurality of sentences into a plurality of sentence groups based on the identified type, and summarize at least one sentence included in each of the plurality of sentence groups based on the user's preference for each type of the plurality of sentence groups.
When a user interaction is input, the processor 120 may update a user's preference for each type of a plurality of sentence groups based on the user interaction.
The operation of the processor 120 will be described in greater detail through various modules of
Referring to
The processor 120 may control the overall operation of the electronic apparatus 100 by executing a module or instructions stored in the memory 110. Specifically, the processor 120 may determine a sequence for data processing by reading and interpreting modules or instructions and controlling the operation of other configurations by transmitting a control signal which controls the operation of other configurations, such as the memory 110.
The processor 120 may identify a type corresponding to a plurality of sentences included in the document by executing the type identification module. For example, when a sentence such as “it was a day when piercing wind like a blade blows” is read out, the processor 120 may identify a representative word such as has “wind”, “blow”, “day”, “blade” from the read out sentence. The representative word is a word representing the meaning of the sentence, and may be used to identify the type of the sentence.
The processor 120 may identify a representative word from a sentence using a method such as a term frequency-inverse document frequency (TF-IDF). The TF indicates the frequency of the word, and the IDF refers to a distinct characteristic of a word. The IDF may be obtained based on the number of the entire documents and the number of documents in which the word appears. The processor 120 may calculate the importance for a plurality of words through the TF-IDF, and may identify a word of which importance is greater than or equal to a threshold as a representative word. However, embodiments in accordance with this disclosure are not limited thereto, and the processor 120 may identify a representative word from the sentence in various ways.
The processor 120 may receive a score about a plurality of types representing a representative word from the memory 110. For example, the processor 120 may read out from the memory 110 a type representing “wind”, type information such as “weather (10)”, “context (4)”, “description (2)”, a type representing “blow”, type information such as “weather (8)”, “activity (8)”, “description (3)”, type representing “day”, type information such as “context (8)”, “time (7)”, “description (5)”, type representing “blade”, type information such as “battle (10)”, “activity (6)”, “weather (2)”, or the like. The number in the parenthesis may refer to a score for each type.
The processor 120 may identify a type corresponding to a sentence based on the read type information. In the above example, when the scores of each type are summed by the processor 120, the score of “weather” is 20, which is the highest, the processor 120 may identify the corresponding sentence as “weather” type.
If the type of the sentence is identified by the type identification module, the processor 120 may update at least one of a plurality of types representing each of the representative words based on the type identified by executing the update module, or a score for each type. In the above-described example, if the type of the sentence is determined to be “weather”, the processor 120 may add “weather” as the type representing “day.” The processor 120 may increase the score of “weather” type of “wind,” “blow”, and “blade.” For example, the processor 120 may increase a score of a “weather” type of “wind” from 10 to 11. However, embodiments in accordance with this disclosure are not limited thereto, and the update method may vary.
The processor 120 may perform a grouping module to identify sentences of which type is the same and the adjacent sentences as one sentence group. In this manner, the processor 120 may distinguish each sentence in the document into several sentence groups. For example, the processor 120 may identify the type of the second sentence when the first sentence is identified as the first type and the second sentence after the first sentence is input. The processor 120 may identify the first sentence and the second sentence as the same sentence group if the type of the second sentence is the first type. If the type of the second sentence is identified as the second type, the processor 120 may identify the first sentence and the second sentence in a different sentence group.
The processor 120, by executing a summary module, may not summarize the first sentence group, if the user's preference for the type of the first sentence group, among the plurality of sentence groups, is greater than or equal to a first threshold value, and if the preference of the user for the type of the first sentence group is below the first threshold value, may summarize the first sentence group. The processor 120 may receive a user's preference of the type of the first sentence group from the memory 110. The processor 120 may also summarize the first sentence group using an artificial intelligence model stored in the memory 110.
The processor 120 may also summarize the first sentence group by stages based on the user's preference. For example, the processor 120 may summarize the first sentence group to a first summary level if the preference of the user with respect to the type of the first sentence group is less than the first threshold and greater than or equal to the second threshold value, and if the user's preference for the type of the first sentence group is below the second threshold value and greater than or equal to a third threshold value, summarize the first sentence group to a second summary level that is simpler than the first summary level, and if the user's preference for the type of the first sentence group is below the third threshold, skip the first sentence group. In this case, the processor 120 may summarize the first sentence group by using a plurality of artificial intelligence models. For example, the processor 120 may summarize the first sentence group to a first summary level using a first artificial intelligence model, and may summarize the first sentence group to a second summary level using a second artificial intelligence model.
The processor 120, when a first sentence group is skipped, may summarize a second sentence group right after the first sentence group based on a user's preference for the type of the second sentence group.
The processor 120 may provide a sentence group to an outputter of the electronic apparatus 100 by executing an output module. The sentence group may be a non-summarized sentence group, and may be a summarized sentence group.
The processor 120 may provide a sentence group or a summarized sentence group to a user via an outputter. For example, if the outputter is a speaker or a display, the processor 120 may output a sentence group or a summarized sentence group as sound through a speaker, or display a sentence group or a summarized sentence group through a display.
The speaker is a component to output various notification sounds or a voice message in addition to various audio data processed by the processor 120; and the display is a component to output various video data processed by the processor 120. The display may be implemented as various types of displays such as a liquid crystal display (LCD) panel, organic light emitting diodes (OLED) display panel, a plasma display panel (PDP), micro LED, laser display, virtual reality (VR), glass, and the like. A driving circuit of the display panel can be implemented using one or more of an a-Si thin film transistor (TFT), a low temperature poly silicon (LTPS) TFT, an organic TFT (OTFT), and a backlight. Further, the display may be implemented as at least one of a touch screen coupled with a touch sensor, a flexible display, a three-dimensional (3D) display, or the like.
The outputter may include an input/output interface, and the processor 120 may provide a sentence group or a summarized sentence group to a device equipped with a speaker or a display through the outputter.
The input/output interface may be one of the high-definition multimedia interface (HDMI), mobile high-definition link (MHL), universal serial bus (USB), display port (DP), Thunderbolt, video graphics array (VGA) port, red, green, and blue (RGB) port, d-subminiature (D-SUB), digital visual interface (DVI), and the like.
As a result, by the operation of the processor 120, a part preferred by a user can be identified in detail, and a part that the user does not prefer may be replaced with a summary or skipped.
When a user interaction is received through an inputter of the electronic apparatus 100 while the first sentence group is output, the processor 120 may change the output state of the sentence group based on the user interaction. For example, when the user interaction “please skip” is input, the processor 120 may stop output of the first sentence group currently being output and may output the second sentence group immediately after the first sentence group. Alternatively, when the user interaction of “please summarize” is input, the processor 120 may stop output of the first sentence group currently being output, and may execute the summary module to summarize the first sentence group and output the summarized first sentence group. If the user interaction is not inputted through the inputter, the processor 120 may output the sentence group provided from the summary module as is.
The inputter may be configured to receive a user interaction, such as a microphone. However, embodiments in accordance with this disclosure are not limited thereto, and the inputter may be any configuration for receiving user interaction. For example, the inputter may be implemented with a camera to receive user interaction, such as a user's motion. Alternatively, the inputter may be implemented as a communication interface and may receive a signal corresponding to a user interaction from an external device. For example, the inputter may include a Bluetooth module and may receive a signal corresponding to the user interaction from a remote control device.
The communication interface is configured to communicate with various types of external devices according to various types of communication methods. The communication interface includes a Wi-Fi module, a Bluetooth module, an infrared communication module, a wireless communication module, or the like. Each communication module may be implemented as at least one hardware chip.
The Wi-Fi module and the Bluetooth module perform wireless communication using Wi-Fi method and Bluetooth protocols, respectively. When using the Wi-Fi module or the Bluetooth module, various connection information such as a service set identifier (SSID) and a session key may be transmitted and received to establish a communication session, and communication information may be transmitted after a communication connection is established. The infrared ray communication module performs communication according to infrared data association (IrDA) technology that transmits data wireless to local area using infrared ray between visible rays and millimeter waves.
The wireless communication module may include at least one communication chip performing communication according to various communication standards such as Zigbee, 3rd generation (3G), 3rd generation partnership project (3GPP), long term evolution (LTE), LTE advanced (LTE-A), 4th generation (4G), 5th generation (5G), or the like, in addition to the communication modes described above.
The communication interface may also include at least one of a local area network (LAN) module, Ethernet module, or wired communication module performing communication using a pair cable, a coaxial cable, an optical cable, or the like.
If the user interaction is input through the inputter, the processor 120 may update the user's preference for the type of the first sentence group based on the user interaction by executing the update module. For example, the processor 120 may reduce a user's preference for the type of the first sentence group when the skip command or the summary command is input while the first sentence group is output. Alternatively, the processor 120 may increase the user's preference for the type of the first sentence group if there is no user interaction while the first sentence group is output.
The processor 120 may output the first sentence group by first considering the user interaction with the user's preference even if the preference of the user with respect to the type of the first sentence group changes according to the user interaction while outputting the first sentence group. For example, when the user interaction “please summarize” is input while outputting a first sentence group, the processor 120 may summarize and output the first sentence group based on the user's preference for the type of the first sentence group, and may update the user's preference for the type of the first sentence group. The processor 120 does not skip the first sentence group even if the user's preference with respect to the type of the first sentence group is reduced to the level to be skipped. However, the processor 120 merely skips the sentence group of the same type as the type of the first sentence group after the first sentence group.
In the example description above, summarization and skip are to be performed in consideration of a user's preference. In this case, there may be a problem that a sentence group which is critical in a document is skipped due to user's preference.
In order to overcome the above problem, an operation to identify a word which is critical in a document, in addition to user's preference, to perform summarization and skip is described.
The processor 120, by executing a critical word identification module, may identify frequency of a plurality of words included in a document and may identify a word of the first number as a first critical word in a descending order of frequency.
By executing a summary module, the processor 120 may summarize at least one sentence included in each of the plurality of sentence groups based on the user's preference and the first critical word for each type of the plurality of sentence groups by executing the summary module.
For example, the processor 120 may not skip the sentence group to be skipped based on the user's preference based on the first critical word. Alternatively, the processor 120 may summarize the sentence group to be skipped based on the user's preference based on the first critical word or output only the sentence included in the first critical word.
The processor 120 may identify the frequency of the plurality of additional words included in the same sentence as the first number of words by executing the critical word identification module, and may identify the second number of additional words in a high order of frequency of re-identification as the second critical words.
The processor 120, by executing a summary module, may summarize at least one sentence included in each of the plurality of sentence groups based on a user's preference, the first critical word, and the second critical word for each type of a plurality of sentence groups. The processor 120 may further use the second critical word to solve the problem of omitting the key content in the document.
In the description above, a user interaction is “please summarize,” “please skip,” or the like. However, the user interaction may be “please do not summarize”, or any other suitable user interaction in accordance with this disclosure. For example, the electronic apparatus 100 may display that the current sentence group is output as being summarized to the user, and if there is a user interaction such as “please do not summarize”, the processor 120 may output the summarized sentence group in a non-summarized state.
As described above, the electronic apparatus 100 may identify a type of each of a plurality of letters, group a plurality of sentences into a plurality of sentence groups based on the identified type, and by summarizing at least one sentence included in each of the plurality of sentence groups based on the user's preference for the types of each of the plurality of sentence groups, may efficiently summarize the document in reflection of the user's preference even when a document is lengthy.
Hereinbelow, various embodiments will be described in greater detail with reference to the drawings.
The processor 120 may identify a representative word from a sentence. For example, the processor 120 may identify representative words such as “wind”, “blow”, “day”, “blade” from the sentence “it was a day when piercing wind like a blade blows” as illustrated in
The processor 120 may identify a representative word from a sentence using a method such as a TF-IDF. Alternatively, the processor 120 may identify a representative word based on a word class of a plurality of words included in the sentence. The processor 120 may identify a representative word from the sentence based on the type information stored in the memory 110. For example, the processor 120 may identify the representative word according to whether the word included in the character is included in the type information.
The memory 110 may store each of a plurality of words and information matched with a type corresponding to each of the plurality of words. In the right side of
The processor 120 may sum up scores by types matched with each of representative words. For example, the processor 120 may sum up the scores for each of types “weather”, “description”, “battle”, “activity” and “context” matched with representative words “wind”, “blow”, “day”, “blade”, respectively, as illustrated in
The processor 120 may determine the type of each of the plurality of sentences included in the document in the manner described in
In this way, a plurality of sentences may be divided into a plurality of groups. Each of the plurality of groups may include at least one sentence, and one group may not include sentences which are not consecutive.
Referring to
If one of the plurality of types is the same as the type of the previous sentence and the other is the same as the type of the subsequent sentence, the processor 120 may include the sentence representing the plurality of types as one of the sentence group of the previous sentence and the sentence group of the subsequent sentence. For example, if the second sentence is determined to be weather and description in the example of
Embodiments in accordance with this disclosure are not limited to the example above. For example, the processor 120 may divide the sentences into one sentence group when types of the sentences are all identical. In this case, if the second sentence is determined to be weather and description in the example of
The type of a sentence may include a main type and a sub type. For example, “weather” may be a main type, and “weather” may include a sub type such as “sunny”, “cloudy”, “rain”, “snow” or the like. In this case, the processor 120 may determine the first sentence group and the second sentence group as one sentence group if the main type and the sub-type of the first sentence group and the second sentence group are all identical. In the memory 110, each of the plurality of words, a main type and a sub-type corresponding to each of the plurality of words, and information matched with a score of each type, may be stored.
The processor 120 may summarize at least one sentence included in the sentence group based on the user's preference for the type of sentence group. For example, as illustrated in
More specifically, for example, the user's preferences may be determined from zero to ten points, and may be initially set to ten points by types. If the user's preference is ten points, the processor 120 may output the sentence group without the summary. That is, the user's preference is not reflected, and the processor 120 may output a document without a summary.
After the preference of the user is changed according to the user interaction, the processor 120 may summarize or skip a sentence group. For example, the processor 120 may summarize the sentence group to a first summary level if the preference of the user is between six and nine points. The processor may also summarize the sentence group to a second summary level if the preference of the user is between the two points and five points, and may skip the sentence group if the user's preference becomes low to a zero point or a one point. For example, the first-step summary of
The processor 120 may summarize a sentence group in various ways. For example, the processor 120 may summarize the sentence group as a ratio corresponding to the user's preference. For example, the processor 120 may summarize a plurality of sentences included in the sentence group by 50% if the preference of the user is between six and nine points, and may summarize the plurality of sentences included in the sentence group by 20% if the user's preference is between two points and five points. The processor 120 may summarize a sentence group based on the number of the plurality of sentences included in the sentence group. In the above-described example, the processor 120 may summarize the sentence group to 50 sentences if the user's preference is between six point and nine point, and the number of a plurality of sentences included in the sentence group is 100, and may summarize the sentence group to 30 sentences if the user's preference is between two points and five points and the number of the plurality of sentences included in the sentence group is 100.
The processor 120 may calculate the importance of a plurality of words included in each of the plurality of sentences to obtain the importance of each of the plurality of sentences. The method for calculating the importance of a plurality of words may use a method such as, but not limited to, the TF-IDF as described above. The processor 120 may summarize the sentence group based on the importance of each of the plurality of sentences included in the sentence group. For example, when a sentence group including 100 sentences is summarized to 50, the processor 120 may summarize a group by obtaining 50 sentences in the order of high importance of 100 sentences, and deleting the rest of the sentence group.
Embodiments in accordance with this disclosure are not limited to the example above. For example, the processor 120 may summarize a sentence group using various method. For example, the processor 120 may summarize a sentence group through a plurality of AI models.
An artificial intelligence model corresponding to each summary level can be stored in the memory 110. For example, a first artificial intelligence model corresponding to the first summary level and a second artificial intelligence model corresponding to the second summary level can be stored in the memory 110. The first artificial intelligence model may be a model that is obtained through AI learning of the sample sentence group and the sentence group in which the sample sentence group is summarized based on the first summary level, and the second artificial intelligence model may be a model obtained through AI learning of the sample sentence group and the sentence group in which the sample sentence group is summarized based on the second summary level.
Embodiments in accordance with this disclosure are not limited to the example above. For example, only one artificial intelligence model may be stored in the memory 110. In this case, the artificial intelligence model may further receive a summary level. For example, the processor 120 may input a sentence group and a summary level of a sentence group to an artificial intelligence model to obtain the summarized sentence group.
An example of second-step summary level is described above. However, embodiments in accordance with this disclosure are not limited to this example. For example, the step and score of a summary level may be implemented in various methods.
The processor 120 may receive user interaction while the sentence group is output. For example, the processor 120 may receive a user interaction of “please skip” while the sentence group is output, as shown in
Although the example of
Alternatively, the processor 120 may vary a change size of a user preference score even when summarizing the sentence group. For example, the processor 120, when a user interaction of “keep it short” is received, may reduce the user's preference score by one point and may output the summarized sentence group. When a user interaction “keep it shorter” is received from a state in which the summarized sentence group is output, the user's preference score may be reduced by two points. That is, the processor 120 may determine a change size of a user preference score based on the number of user interaction input while outputting one sentence group.
Alternatively, the processor 120 may receive direct user interaction with respect to user preference. For example, the processor 120 may reset the user preference for the type of the sentence group if there is a user interaction “please reset preference” while outputting the sentence group.
The processor 120 may provide a user with information of outputting the summarized sentence group. For example, the processor 120 may inform the user that the currently output sentence group is summarized by turning on a light emitting diode (LED) lamp provided on the electronic apparatus 100. In this case, the user may want to listen to an original copy of the summarized sentence group, and the processor 120 may stop the output of the summarized sentence group when the user interaction “please do not summarize” is received, and output the sentence group before the summary.
The processor 120 may identify the frequency of a plurality of words included in the document and identify the first number of words as a first critical word based on the frequency of the plurality of words. The processor 120 may also summarize at least one sentence included in each of the plurality of sentence groups based on the user preference for types of each of the sentence group and the first critical word.
For example, the processor 120 may identify the frequency of a plurality of words included in the document and arrange the plurality of words in a descending order, as shown in
The processor 120 may re-identify the frequency of the plurality of additional words included in the same sentence as the first number of words, identify the second number of additional words as the second critical word based on the frequency of the plurality of additional words, and summarize at least one sentence included in each of the plurality of sentence groups based on the user's preference, the first critical word, and the second critical word for each type of the plurality of sentence groups.
The processor 120 may summarize a sentence group by reflecting a first critical word and a second critical word differently. For example, the processor 120 may exclude a sentence including even one of a first critical word among at least one of the sentences included in the sentence group from a subject of summary or skip. In this regard, the processor 120 may exclude a sentence including two or more second critical words among the at least one sentence included in the sentence group from the subject of summary or skip.
The operation may be performed on a unit of a sentence group other than a sentence. For example, the processor 120 may not summarize or skip the sentence group if the first critical word in the sentence group is greater than or equal to the first number. The processor 120 may not summarize or skip the sentence group if the second critical word is greater than or equal to the second number which is greater than the first number.
The processor 120 may assign a different weights to the first critical word and the second critical word, and may not summarize or skip the sentence group if the total sum of weights in the sentence group is greater than or equal to the threshold. For example, the processor 120 may assign weight 2 to the first critical word and weight 1 to the second critical word, and may calculate a total sum of the weight of the first critical word and the second critical word included in the sentence group. If the total sum of the calculated weights is greater than or equal to 50, the processor 120 may not summarize or skip the sentence group.
First, a type corresponding to each of the plurality of sentences included in the document is identified in operation S610. The plurality of sentences are grouped into a plurality of sentence groups based on the identified type in operation S620. At least one sentence included in each of the plurality of sentence groups is summarized based on a user's preference for each type of each sentence group in operation S630.
The step of, based on a user interaction being input, updating a user's preference for each type of the plurality of sentence groups based on the user interaction may be further included.
The summarizing step in operation S630 may include outputting the first sentence group in a non-summarized state if the user's preference with respect to the type of the first sentence group among the plurality of sentence groups is greater than or equal to the first threshold value, summarizing the first sentence group when the user's preference for the type of the first sentence group is less than the first threshold value, and outputting the summarized first sentence group.
The updating step may further include updating a user's preference for the type of the first sentence group based on the user interaction when the user interaction is input while the first sentence group is outputted.
The updating step may decrease a user's preference for the type of the first sentence group if the user interaction is a skip command or a summary command, and if there is no user interaction, the user's preference of the type of the first sentence group may be increased.
The summarizing in operation S630 may include, based on the user's preference for the type of the first sentence group being less than a first threshold and greater than or equal to a second threshold value, summarizing the first sentence group in a first summary level, based on the user's preference for the type of the first sentence group being less than a second threshold value and greater than or equal to a third threshold value, summarizing the first sentence group to a second summary level simpler than the first summary level, and based on the user's preference for the type of the first sentence group being less than the third threshold, skipping the first sentence group and outputting the second sentence group immediately after the first sentence group.
The step of identifying a frequency of a plurality of words included in the document and identifying a first number of words as a first critical word based on the frequency of the plurality of words are further included and the summarizing step in operation S630 may include summarizing at least one sentence included in each of the plurality of sentence groups based on the user's preference and the first critical word for each type of the plurality of sentence groups.
The method further includes re-identifying a frequency of a plurality of additional words included in the same sentence as the first number of words and identifying a second number of additional words as a second critical word based on the frequency of the plurality of additional words. The summarizing step in operation S630 may include summarizing at least one sentence included in each of the plurality of sentence groups based on the user's preference, the first critical word, and the second critical word for each type of the plurality of sentence groups.
The identifying step in operation S610 may include identifying a type of one sentence based on a score for a plurality of types representing each word included in one sentence among the plurality of sentence groups.
The method may further include updating at least one of a plurality of types or scores for each type representing the word included in one sentence based on the identified type if the type of one sentence is identified.
The grouping step in operation S620 may include dividing a plurality of sentences into a plurality of sentence groups by identifying at least one sentence adjacent to each other and having the same type.
According to various embodiments, the electronic apparatus may group a plurality of sentences included in a document into a plurality of sentence groups according to a type, and summarize each of the plurality of sentence groups based on a user's preference for each type of the plurality of sentence groups, thereby enabling a document to be summarized reflecting the preference of the user.
The electronic apparatus may update a user's preference for each type of a plurality of sentence groups according to user interaction, and may actively reflect a user's preference.
